sounds like the line has broken and will need replaced its a fairly easy process to replace the fuel lines on them. just replace one line at a time that way you don't accidentally mix up which side of the carb that they connect to. some models have a small barb type fitting that the line will connect to inside the tank but on most the line is just a snug fit through the holes in the tank so that it doesn't leak. if you need any tips on installing the new line let me know.
